10 Chilli- (Cl. 33-4) This invention relates to the spinning ofartiflcial filaments, strands, cords. threads or the like. Moreparticularly this invention relates to a device employed to centerspinning tunnels in spinning buckets or the like. a

It is of great importance that spinning funnels are centered in spinningbuckets. These spinning funnels reciprocate longitudinally in therotating spinning bucket. As the tunnel reciprocates;

thread or the like is led through it and due to;

the centrifugal force created by the rapidly ro tating spinning bucket;it'is thrown to the outer periphery of the spinning bucket and evenlywound into a cake. However it-theiunnel is not properly centered, thethreads or the like will not be wound symmetrical y and will becometangled making it. almost impossible to unwind formed cakes.

Each spinning bucket has a colored circular mark imprinted in the centerof'its base; This circular mark is substantially-the same diameter asthe spinning tunnel at the point where the thread emerges. Heretofore aflashlight was directed through the funnel to determine the relationshipbetween the beam of light and the im-- printed circular mark. If itwasproperly centered the beam of light would be coincident with thecircular mark or concentric with the circular mark if the circular markwas 'of a greater diameter than the beam of light. However using. aflashlight was makeshift at best and a greater percentage 01' the timethe spinning tunnel was improperly centered. This was due to thediilusion 01' the fl'ashlight's rays and also due to the fact that itwas difllcult to center the funnel when it had to be adjusted whileholding the flashlight which made this method slow and tedious. Thesedisadvantages of centering are,

overcome in the present inventionX The primary object of the presentinvention is to provide an improved device for accurately centering aspinning funnel in a spinning bucket or the like.

Other objects and advantages of the present invention ,will becomeapparent from a study 01' the following drawings and descriptionshereinafter.

Inthe drawings Figure 1 is a top yiew of av preferred embodiment of thepresent invention.

Figure 2 is a side elevation oil-igure 1.

Figure 3 is a side elevation partly in section of a preferred embodimentof the present invention takenv along line III-III of Figure l but witha spinning tunnel in position.

As shown in Figures 2 and 3, reference character l represents thehousing of the present invention. Extending from the lower portion ofthe housing I is an annular projection 2 into which an annular adaptermember I is seated. This adapter 3 is readily interchangeable'with otheradapters having the same outside diameter but a diilerent insidediameter. The variable inside diameters oi' the adapters compensate forfunnels oi diiierent diameters. The housing I is supported in place bythe flared end In or the funnel 4 which his snugly inside the adapter 3and against the lower annular seat la at the lower end of the housinginside the adapter and prevents any wobblingor tilting of the housing.Said funnel I is supported by a funnel bracket arm 43.

Directly over the funnel on a common centerline and supported in thehousing 1 is a microscope lamp lens system 5 consisting of two or morelens elements. Although it is not shown the lens system may include adiaphragm to vary the size of the beam of light projecting through thefunnel. This lens-assembly 5 may or may not project into the annularprojection 2. However as shown in this embodiment it extends from apoint part way below the housing I, through the more or less centralbore Sa'in the housing to a point a suitable distance below the lightsource 8. The lamp 0 is held in its socket 1 which is suitably securedinside the cover member 8. As shown in Figure 1 the cover member 8 issecured to the housing I by four screws s, III, II and i2.

However it is to be understood that this cover may be attached in anyother way such as by clamps, studs or the like.

The screws 9, i0, II and it also center the light source 8, relative tothe bore so that it is on the centerline common to the microscope lenssystem 5 and the funnel I. v with the microscope lens system I so placedit parallelizes the rays from the light source 6 and projects themthrough I the funnel l with -a minimum of difiusion and so the cover Iover the dry cell I4 is also counterconcentrates them at a point H onthe base 42 of the spinning bucket.

Placed on opposite sides of the microscope lens system i in the nouskigare two dry cells It and I4. The dry cell It is contained in acylindrical recess I! that is countersunk at its base to form a smallercylindrical recess l'l into which is placed a spring It. Similarly thedry cell It is contained in a cylindrical recess it which is countersunkto iorm another cylindrical recess is into which a toggle switch 20 issecured.
